To all whom it moy concern:

Be it known that I, EnN-s'r HUGO Hau- MANN Knauer, u. citizen of theEmpire of Germany, residing at Hamburg, Germany, have invented certainnew and useful I lnprovements in Apparatus for Quenchnig IncandescentMaterials, of which the followin is a full, clear, and exactdescription.

is invention relates to apparatus -for quenching incandescent materials.and is purticularly adapted for dealing with cokeni large quantities,such as produced, for lnstance, 1n retorts working with large charges.

The object of this invention is to effect 1n as speedy und thoroughmanner as possible the quenching of such large quantities of coke 1n thetrough of a'traveler movable on rails in front of the retorts. As insuch case the walls of the quenching trough are apt to be damaged bybecoming excessively hot owing to their contact. with the incandescentcoke, it has already been suggested to make the lateral walls of thetrough hollow and to cool them by water circulation, the upper Wallshaving previously been in the form of a hood above the trough andprovided with a longitudinal slot through which water contained thereincould flow on to the coke in the trough.

According to this invention the Water- ]aclreted quenching trough is ofthe special construction hereafter described and apparatus is providedfor conveying water to the coke in the trough so as to insure the mostthorough and rapid quenching thereof.

A coke quenching apparatus constructed according to my invent-lon isillustrated in the accompanying drawings in which- Figure l is avertical sect-ion of the apparatus mounted on the traveler, and F ig. 2en elevation of the same, partly in section, seen from the left handside.

The quenching trough 1 is mounted in thc center of a traveler which ismovable, as is well known, in front of the gas generating retorts. Thelateral walls Q as Well as the bottom 3 of the trough are formed double,and adapted to have water circulated throu h them for cooling purposes.The Intera walls 2 of the extinguishing trough are sti'ened inside bymeans of ribs which, however, are of such construction that the waterused for cooling the walls can freely flow through the hollow space ofthe walls.

The trough is open at the top and openings are formed in the upperportions of the side walls Q through which cooling Water can pass intothe interior of the trough 1.

The wall which is on the left hund side in Fig. 1 is provided at itslower end with a movable discharge door 4 which also has double wallsand can he opened or closed at will from the central platform of thetraveler by means of a sprocket and chain gear G and 7 to empty thecontents of the trough. The gear chains 7 pass over the sprockets Smounted on the outer ends of thc door pivot.

vater is supplied to the walls 2 and to the bottom of the trough througha pipe 9 lead ing into the bottom of the trough and suitab y connectedwith a source of water supply to permit the traveler to he shifted,while the hollow door l is supplied with water by means of a flexiblepipe 10 connected to the upper p ortion of the corresponding lateralWall 2. The door 4 is provided near its upper end with openings 11whereby the coke contained in the lower portion of the trough 1 orfalling from the same, is sprinkled with water.

In the construction illustrated, there is further provided in theinterior of the trough 1 a hollow cross-bean1 12 to which Water issupplied through pipes 13 from the hollow lateral walls 2, this Waterpassing through lateral openings 14 in the beam to the heart ofthe massof coke in the trough. The beam 12 is at the same time utilized as abale, since it separates and divides the coke falling on it from theretort into the trough 1, and thus assists its quenching.

In front. of that lateral wall 2 of the trough 1 having thedischarge'door, a partition 15 is provided at. the required distanceforming an exhaust passage for the steam or fumes, the upper portion ofwhich opens into the central tower-like chimney 1G of the apparat-usthrough which steam generated during the extinction of the colte iscarried up- Ward in the woll known manner, thus protectng the attendantsfrom danger.

The trunsfcr of colic from the retorts to the quenching trough i isclicctcd by means of chutes 1T arranged at one or both sides ofthetruvclcrand (.ipcningintothc trough l.

in operation the coke discharged into the trough 1 will be quenched allover its upper surface by water from the openings 5 in the waterescaping through the openings 11 of the watercooled door 4. Owin totheeoke being simultaneously c xtinglus ed through out, quenching takesglace in a rapid and p "z thorough manner.

i owing to the cooling' of all the walls, as well as of the bottom anddischarge door of the n the other hand,

trough, the latter is not excessively heated by the incandescent cokeand is not therefore damaged.

The apparatus illustrated is also provided with mechanism whereby themovement of the traveler can be controlled from the central platform foractuating the discharge door and the door of the retorts it is desiredto empty.

The platforms of the traveler are arranged in such a manner thatcleaning of the retorts or repairs thereto can be conveniently effected.

Finally, the apparatus illustrated is adapted to carry any mechanism orparts required for attending to the retorts, but such mechanism forms nopart of the present inven tion and is not therefore shown or described.
